[A/S] Yukon ¾ ton XL with a Vortec 8100 V8

Ron,
I have this TV with a 3.73 rear end.
Mileage while towing a 25' Excella has ranged from a low 7.5 to a high
of 10.3. The difference being how fast we tow and the presence of a
strong head wind on one trip.

Highway mileage not towing is 14-15. City mileage is poor at about 11.

So, the mileage is not great but it sure tows nicely :-)
